Cauliflower in a Zone 8 season
Zone 8 gives about 224 frost-free days. Cauliflower needs roughly 70 days from transplant. That leaves about 154 days of slack, so there is room for a late start or a second planting.
How to grow cauliflower
Start seeds indoors about 4 weeks before planting out, timing it so the heads form in cool weather. Steady moisture and cool weather make tight white heads, while heat leaves them loose.
